Influence of Thermo-Chemical Treatment on the Surface of CP Titanium
Advanced Materials Research, 2014The effect of the holding time on the surface hardening of commercially pure titanium (CP-Ti) by thermo-chemical treatment (TCT) process was studied in the present paper. Surface treatments with three different times were carried out and investigated. The TCT process using nitrogen gas was carried out under vacuum atmosphere in treatment time (0.5, 1 ...

Effects of Thermo-chemical Pre-treatment on Bamboo for Biogas Production
Indian Chemical Engineer, 2015AbstractThe objective of this work was to develop various pre-treatment process, i.e. Ca(OH)2, NaOH, ammonium carbonate, H2SO4, maleic acid and combination of hydrothermal with H2SO4 in a batch anaerobic digestor of bamboo. Biogas efficiency of bamboo with and without pre-treatment was evaluated. The highest biogas production and methane yield were 820

Thermo-chemical Seed Treatment
Nature, 1954NEWHOOK1, using the technique of Baylis2, reported that a hot-water steep of 10 min. at 52.8° C. controlled seed-borne pasmo (Sphaerella linorum Wollenw.) in seed-lines of linen-flax (Linum usitatissimum L.). Watson et al. 3 have recently reported the use of carbon tetrachloride as a suitable material in place of water for heat treatment of peas and ...

Thermo-chemical pre-treatment to solubilize and improve anaerobic biodegradability of press mud
Bioresource Technology, 2013Different pre-treatment severities by thermo-alkaline conditions (100°C, Ca(OH)2) on press mud were evaluated for different pre-treatment time and lime loading. COD solubilization and the methane yield enhancement were assessed. The biochemical methane potential was determined in batch assays under mesophilic conditions (37±1°C). The best pre-treatment

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2014
Sludge is a semi-solid residue produced from wastewater treatment processes. It contains biodegradable and recalcitrant organic compounds, as well as pathogens, heavy metals, and other inorganic constituents. Sludge can also be considered a source of nutrients and energy, which could be recovered using economically viable approaches.

Characterization of Biogenic Silica Generated by Thermo Chemical Treatment of Rice Husk
Particulate Science and Technology, 2013This study presents two routes to produce amorphous silica from an Egyptian rice husk under conditions optimized for least environmental impact and low cost. The first route includes thoroughly washing of the husk sample with water, dry milling and leaching with citric acid.

Dried grass silage (GS) was pre-treated at different NaOH loading rates (1%, 2.5%, 5% and 7.5% by volatile solids (VS) mass in grass silage) and temperatures (20 °C, 60 °C, 100 °C and 150 °C) to determine effects on its bio-degradability in terms of the hydrolysis yield and degradation of ligno-cellulosic materials for biogas production.

Limitations for heavy metal release during thermo-chemical treatment of sewage sludge ash
Waste Management, 2011Phosphate recycling from sewage sludge can be achieved by heavy metal removal from sewage sludge ash (SSA) producing a fertilizer product: mixing SSA with chloride and treating this mixture (eventually after granulation) in a rotary kiln at 1000 ± 100°C leads to the formation of volatile heavy metal compounds that evaporate and to P-phases with high ...
